How do I change the color for a plot in a for loop?

Hi, I am trying to change the color of this dotted plot in this for loop. I want to change it to a brown color, but whenever I try hexadecimal or RGB color codes, the dots vanish. Is there a different way I should be trying this instead?

You seem to be plotting point, not lines, in the loop, and to do that it is necessary to specify a marker.

Perhaps this —

plot(R(1), R(2), 'p', 'MarkerFaceColor',[0.3020 0.2775 0.1647], 'MarkerSize',20)

Experiment to get different results.

Awesome! I tried it out, and my dots have finally reappeared. Thank you for your help, Star Strider!

In order for 'MarkerFaceColor' and 'MarkerSize' to have any effect, you must plot with some marker specified.

First, with no marker specified, nothing shows up:

figure
plot(2,2,'MarkerFaceColor',[0.3 0.2 0.1],'MarkerSize',20)
xlim([0 3])
ylim([0 3])

Now, with a marker specified:

figure
plot(2,2,'Marker','o','MarkerFaceColor',[0.3 0.2 0.1],'MarkerSize',20)
xlim([0 3])
ylim([0 3])

Thank you Voss, this worked for me. My dots have reppeared!
